Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725738, here are decompositions:

5 + 8725733 = 8725738
107 + 8725631 = 8725738
167 + 8725571 = 8725738
191 + 8725547 = 8725738
227 + 8725511 = 8725738
239 + 8725499 = 8725738
257 + 8725481 = 8725738
317 + 8725421 = 8725738

Showing the first eight; more decompositions exist.
